The inner ends of the levers 115,115 aremade substantially U-,

shaped and provided at their extreme ends with rollers 118, 118 adapted to engage the locking flaps of the carton ends and press the same into the slits in the coiiperating end members, the carton ends belng permitted to yield sufficiently for this purpose owing to the recesses 41, 41 provided in the opposite ends of the heads 40 carried by the sprocket chains 38, 38. Upon the. front transversev member 28 (Figs. 2 and 6) are provided bearings 119, 119 in which is supported a shaft 120 having fixed thereon inwardly extending guide arms 121, 121 which have their free ends disposed substantially below the lower ends of the vertical guides 106, 106, and provided in their upper surfaces tapering grooves 122, 1'22 'a'da-pted to receive the tucking tongues of the 'car ton and guide the same into position to be forced into the slit in the coiiperating end member to hold the carton to its shape.

The bearings 111, 111 are further provided with inwardly extending projections 123, 123 at the inner ends of which are pivotally supported levers 124, 124 provided at their lower ends with rollers 125, 125 adapted to ride upon the cam surfaces 109, 109, and the upper ends of said levers are pivotally connected by means of links 126, 126 to the undersides of the guide arms 121, 121 mounted on the shaft 120.

The rollers 125, 125 at the lower ends of the levers 124, 124 are held normally in contact with the cam surfaces 109, 109 by means of coiled springs 127, 127 each of which has one end secured to the underside of-the top plate 27, and its other end secured to the lever 124.

At the lower portion of the frame 25 (Fig. 1.) in line with the opening 63 in the top plate 27, are provided bearings 130 in which are transverse rollers 131, over which passes an endless convcyer or belt 132 to receive the cartons as the same are removed from the heads 40, 40. 133, 133, denote inclined longitudinal guides arranged at each side of the belt or conveyer 132.

Assuming the machine to be in operation, and the endless sprocket chains 38, 38 carrying the heads or formers 40, 40 to be moving in the direction of the arrows 0 (Fig. 1) the operation of setting up a carton and at the same. time providing it with a'protective lining consisting of a sheet 136 of paper or other material, preferably rendered impervious to moisture, is as follows: A carton blank 135 is first placed in position within the guide 65, and a sheet of protective lining 136 properly adjusted in position thereon. As soon as the bottom of one of the heads or formers 40 about come into contact with the carton blank 135, and its protective sheet 136 thereon disposed within the guide 65 on the top plate 27 it] will cause the same to be pressed downwardly and into the longitudinal opening 63 in said top plate 27. However, just'before the block or head40 comes into engagement with the upper surface of the carton blank and its lining, the hinged plate or member 89 will be raised through the action of the cam 80 lifting the rod 82, which in turn partially rotates the shaft 84 carrying the plate or member 89 by means of the crank arm 85, and by the time the bottom-of said head 40 is on about a line with the top plate 27 the said hinged plate or member 89 will have been brought to a vertical position and hold the front member or portion of the carton. pressed against the front surface of the head orformer 40. When the hinged plate or member 89 has assumed a position about 'midway between its horiaontal and vertical positions (at about an angle'of 50 degrees), the hinged wing sections or end members 102, 102 will be folded inwardly toward the end of the head 40 by the action of the cam 91, acting upon the rod '93, which in turn partially rotates the arm 96, secured to the left hand end of the shaft 95, and also partially rotates the arm 97 connected to the lever 98, which latter has its upper end in pivotal engagement with the inner opposing ends of the levers 99, 99, mounted in bearings 100, 100 secured in the underside of the plate 89. The outer ends of said levers 99, 99 are pivotally secured to bearings in the underside of the wing sections 102, 102. By the time the hinged plate 89 has assumed the vertical position as aforesaid, the wing sections or end members 102, 102 will serve-to press the front end flaps ofthe carton containing the slits inwardly against the ends of the head or former 40. The position of the parts at about this time will be asillustrated in Fig. 11. Hereupon the head 40 with its carton blank begins to enter the longitudinal opening 63, and the bottom end flaps are brought into engagement with the upper outwardly curved ends of the folding guides 106,106, and cause the same to fold said bottom end fla s .upwardly against the folded front en flaps, as the carton is carried downwardly into the horizontal opening 63, and caused to assume the position illustrated at Fig. 12. At

about this time the free ends of the fingersv 49, 49 will be caused to move downwardly toward each other until their lower transverse edges assume a position at an angle of about 45 degrees to the top plate 27, by the action of the cam 42 on the shaft 35. This causes the end. of the vertical member of the bell crank lever 44 to move inwardly toward the shaft 35, and the forward end of its horizontal member to descend, and cause the links 47, 47, which are connected at their lower ends to theangular projections 50, 50 of the fingers 49, 49, to engage the protective linin 136, atthe junction of the carton back wit its end'flaps, and hold said protective lining distended for the subsequent folding operation. At thisperiod of the folding operations, the bottom of the carton is on about a line with the front-edge of the inclined portion 64 of the top plate 27, and as the head 40 descends farther, the back and cover members of the carton are brought to a position at right angles to the bottom of the carton, and against the rear side of the head 40 by their contact with the flange portion 64depending from the front, edge of the inclined entrance portion 64, as illustrated at Fig. 13. Hereupon the lower edges" of the backend flaps with their" tucking tongues come into engagement with the upper ends of the vertical guides 7 7, 77. and

the same are folded against the upturned bottom end flap thereof, as illustrated at Fig. 14. The head 40 with its carton and protective lining thereon thereupon continues to descend untilthe upper edge of the cover member of the carton comes into position below the depending flange 64, arranged at the front edge of the inclined portion 64 of the top plate 27, whereupon the said cover portion and back portion of the carton with its lining will be caused to fall rearwardly against the inclined guide portion 67 by the action of the grooved arms 121, 121 engaging the tucking tongues of the back end flaps of the carton and guiding the same into position to be inserted into the slits in the front end flaps with the next step in the operation. The grooved arms or 121, 121 are actuated by means of the levers 124, 124 which have their upper ends connected to said arms or guides 121, 121, by links 126, 126, and their lower ends provided with rollers 125, 125 working upon the cams 109, 109 on the driving shaft 78. At about the same time, the rollers 118, 118, carried by the inner ends of the bell crank levers 115, 115, will be forced into engagement with the slotted front end flaps, and

open the slits therein for the' reception of the tucking tongues of the rear end flaps. This operation being produced by the action of the levers 110, 110 which have their upper ends pivotally connected to the bell-crank levers 115, 115 by links 114, 114 and their lower ends provided with rollers 112, 112, working upon the cams 108, 108, on the driving shaft'78..' At this stageof the folding operation the parts will be in position in- (heated at Fig. 1.5. Hereupon the back member of the carton and its cover are again brought to a vertical position by means of the hinged plates '69, 69, which are arranged at the lower edge of the inclined guide portion 67, and actuated by the cam 52 fixed to the shaft 31, the rod 53 and its roller 55 engaging said cam, together with the arm 74 fixed to the shaft 71 carrying the depending arms 72, 72, which have their lower ends connected by links 73, 73,to said hinged plates 69, 69, adjacent to their upper edges. As the back and cover member of the carton are thus brought to the vertical position, the locking tongue arranged on the back end flap member is inserted into the slit in the front end flap by the action of said hinged plate in 006 eration withthe rollers 118, 118, carried by the bell-crank levers 115, 115; the several end flaps being capable of yielding inwardly sufliciently for this purpose owing to the recesses 41,,41 provided in the opposite ends of the heads 40, 40. This completes the operation of folding and locking the carton to its shape and form, and the carton thereupon continues to be carried downwardly upon its head 40 to the point where the upper edge of the front member or flap of the carton comes into position at a point just below the rollers 105, 105 carried at the lower ends of the front vertical guides 103, 103. At about this time the segmental gear 61 comes into engagement with the segmental gear 57 carried upon the shaft 31, and causes said gear and the finger 62 carried thereby to be partially rotated, and in being so rotated, bring the free end of said finger 62 into the vertical opening 41 in the head 40, and into contact with the upper edge of the upstanding cover portion, and knock the carton from its head or former 40. The open carton, in the form shown at Fig. 20, then drops upon an endless conveyer or belt 132 arranged in the lower part of the machine and is then carried away to receive'its contents and be closed. As soon as thecarton has been knocked or removed from the head 40 the finger 62 will be restored to its initial position against the buffer 75 by the action of the spring 62. Hereupon the operation just described will be repeated as the next head 40 comes into engagement with a new carton and lining placed within the guide 65 on the top plate 27, and the operations continued as long as the machine is kept in operation and blanks supplied to the top plate 27. v

The particular form of carton and the method of folding the same is given merely for the purposes of illustration, and any well known form of carton having tucking and locking flaps may be used, and the machine adapted thereto without departing from the spirit of the invention, and in the modification about to be described I show a construction wherein the order of folding the end flaps is varied; that is to say, the bottom end flaps (which are rectangular in this instance) are first folded upwardly adjacent to the ends of the head, and subse quently in the course of the operation of the machine the front end flaps'and the back end flaps are then folded and locked together. In said modification, as illustrated at Figs. 18 and 19, the 'mainoperating parts of the machine are substantially as above described, except that in this modification the hinged plate 89, which is mounted upon the shaft 84, is not provided with the wing sections 102, 102 for folding the frgnt end flaps of the carton. The said plate 89 is directly operated by means of a link 150 which is secured to the underside thereof, and to the slotted end'of the arm 97 on the shaft 95. Adjacent to the opposite ends of the 'opening 63 in the top plate 27 are provided short guides 151, 151which are secured to the top plate 27 in front of the inclined portion 64, and have their upper ends bent outwardly toward the ends of the machine, said guides being adapted to engage the bottom end flaps of the carton and fold the same against the ends of the head 40 as the carton blank is carried downwardly uponsaid head, as shown at Fig. 21. Upon the underside of the top plate 27 adjacent to, and below the front edge of the opening 63 therein are folding guides 152, 152 which have their upper ends secured to the underside of the top plate 27. Said guides 152, 152 have their upper portions 153, 153 diagonally. beveled or curved downwardly and inwardly toward the opening 63in the top plate 27, and are adapted to engage the front end flaps of the carton blank and fold the same inwardly against the folded bottom end flaps as shown at Fig. 22, and hold the same in position to be engaged by the succeeding folding mechanism. Directly to the rear of said guides 152, 152 and below the guides 1.51, 151, are arranged guides 7 7 7 7 which have their upper ends secured to the depending flange 64 and theirlower ends secured to brackets 154:, 154, at the lower ends of the inclined guide portion 67. The said guides 77 77*, have their upper ends beveled inwardly and forwardly and are adapted to engage the back end flaps of the carton and fold the same against the folded front andbottom end flaps of the carton blank, as shown at Fig. 23, and hold the same in position to be acted upon by the tucking mechanism in the manner here.-. inbefore described, by means of which the tucking tongue of the back end flap is inserted into the slotted front endflap and the carton thereby locked to its'shape.

It will, of course, be understood that in the successive steps or operations of folding a carton the protective lining is folded simultaneously therewith. Further, it is to be noted that where a carton is to be formed without an inner protective liningthe operation above described is performed in the same manner with the exception that the fingers 49, 49,,cam 42, and the parts intermediate the same, while operating as heretofore described, perform no function when an unlined carton is being made.
